Easy Fill Tire Alert Function

WARNING: This page is about a different car, the 2018 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: When beginning tire inflation, it takes a few seconds for the Easy Fill Tire Alert to function. If there is no response for approximately 15 seconds or more, cancel the Easy Fill Tire Alert function and move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.

The Easy Fill Tire Alert function operates only when the select lever position is in P-range with the ignition switch ON.
This function informs the driver with a visual and audible indication that the recommended COLD tire pressure has been reached.
The hazard warning lamps blink when the recommended COLD tire pressure has been reached. After the recommended COLD tire pressure has been reached, the horn sounds once and the hazard warning lamps stop blinking.

If the tire pressure value is equal to or greater than 30 kPa (0.31 kg/cm ² , 4 psi) more than the recommended COLD tire pressure, the hazard warning lamps flash and the horn sounds three times.
To return the tire to the recommended COLD tire pressure, deflate the tire until the horn sounds once and the hazard warning lamps stop blinking.
